目前，"数字化经济"的图景已经浮现,电子商业、电子银行和电子货币的研究、实施和标准化正在紧锣密鼓地进行中。许多传统上基于纸面的,常常需要签名盖章的重要凭证，诸如纸币、存单、支票、股票、公函、合同、法律文书、身份证件、学历证书等等,已陆续转化为数字电子媒体的形式出现。这种转化方兴未艾,前景辉煌。
具有Feistel 结构的秘密密钥分组密码体制的DES算法在POS、ATM、磁卡及智能卡（IC卡）、加油站、高速公路收费站等领域被广泛应用，如信用卡持卡人的PIN的加密传输，IC卡与POS间的双向认证、金融交易数据包的MAC校验等。
本文将详加介绍DES算法和其它数据加密算法，并实现基于DES算法的文件加密平台。

Currently, the diagram view of "the numeral turn economy" have been already present, electronics business, electronics bank and cyber cash of research, implement with standardize just at tight Luo the airtight drum ground be in progress.Many tradition top according to paper noodles of, usually demand signature stamp of importance certificate, such as the banknotes, receipt for deposit, check, stock, official letter, contract, law clerk, identity certificate, educational background certificate...etc., already continuously conversion for numeral the form of the electronics medium appear.This kind of conversion is on the up, foreground brilliancy.
Have Feistel structure of secret airtight key cent set the DES calculate way of the password system is in the realms, such as the POS, ATM, Ci card and the intelligence card(IC card), gas station and superhighway toll station...etc. drive extensive application, such as encrypt of the credit card card holder's PIN deliver,
